Tips when playing Lucian:

Ardent Blaze actually explodes in a star pattern. Try to line it up so the spokes hit enemy champions.

Once you have chosen an angle for The Culling, you cannot change it. Pick your moment well!

Because of Lightslinger, Lucian benefits more from Attack Damage than he does from Attack Speed.

The story of Lucian:

Once a Sentinel of Light, Lucian is a grim hunter of undying spirits, pursuing them relentlessly and annihilating them with his twin relic pistols. Consumed by the need to avenge his dead wife, he will not rest until Thresh, the specter who holds her soul, is destroyed. Merciless and single-minded, Lucian allows nothing to stand in the path of this vengeance—anyone or anything foolish enough to try is blown away by an overwhelming barrage of magical gunfire.
